Yesterday, speedrunner DraQu beat the sci-fi shooting sim Prey in just 45 minutes. Today, he’s knocked it down to 20. This is a game that has been out for three days.

You’re safe to watch the first few minutes without spoiling too much, just to see how he pulled it off. The short version: DraQu uses GLOO to build blocks in the air that he can use to reach inaccessible locations, clip through walls, and generally break the whole game. The highlight is a four-minute climb that takes him all the way up to the arboterum. (Stop at around 8:00 if you don’t want any spoilers.)

For context, Prey has taken most people around 20 hours to finish. But Talos I is way less scary when everything’s broken.
